CHARLES A. TATUM, OF NEW YORK, N. Y., ASSIGNOR TO WHITALL, TATUM & 00.,OF SAME PLACE.

THERMOMETER-CASE.

SPECIFICATION forming part of Letters Application filed February 24,1886.

To all whom it may concern:

Be it known that I, CHARLES A. TATUM, of the city of New York, countyand State of New York, have invented an Improved Ther- 5 mometer Case,ofwhich the followingis a complete description, reference being had to theaccompanying drawings, in which Figure 1 represents a side view of myimproved thermometercase, showing it closed.

[ Fig. 2 is a side view of the same, showing it partly open. Fig. 3 is aside view of the same, showing it'wholly open. Fig. 4 is a centralsection of the upper part of the same.

The object of this invention is to prevent 1 the loss of cases forthermometers, and the like, and of their covers when the contents havebeen taken out.

As heretofore constructed, the cases or shells forthermometers oranalogous articles are provided with detachable covers, and when aphysician, for example, who carries such an instrument takes the sameout of the shell for use he is liable to place the shell and coverseparately on a suitable support,whence either 2 one or bothare apt toroll off or become lost or misplaced.

By my invention, which consists in pivotally connecting the tubularcover of a shell having a shoulder andrecess with the body thereof,their complete separation is prevented,

and the annoyance above stated obviated.

Moreover, by the use of such a pivotally-connected cover the cylindricalshell is prevented from rolling when open.

In the drawings, the letter A represents a shell of cylindrical or otherform. At its open end this shell has a projecting neck, a, which isslotted longitudinally, as at b. Into theslots b are receivedinwardly-projecting pins (1, that Patent No. 343,678, dated June 15,1886 Serial No. 192,979. (No model.)

extend from ears 6, that are formed at the 40 lower end of the tubularcover 13. The shoulderfof the shell A, where the necka joins, 1s of sucha shape as to conform to the shape of the ears 6, so that when the coverB is slid down, as in Fig. 1, said ears will enter nto 5 the recesses ofsaid shoulder, and make a tight joint. These recesses are shown at g.

WVhenthe shell is to be opened, the covcrB is slid up until the pins (1reach theupper portions of the slots 1), and thereupon the cover B isturned over sidewise on said pins and slid down again until it reachesthe position shown in Fig. 3. In this position the shell, when placed onany support, will be unable to roll off, and the entire arrangementissuch as to prevent the separation of the cover from the body of theshell.

The upper end of the neck amay have tapered or rounded edges to allowthe cover to be easily turned from the upright position which is shownin Fig. 2 into the side position shown in Fig. 3.

The shell A may be made of metal and 111 one piece with the neck a, orthe neck'a may be slid or sprung into the body of the shell, in 6 whichcase the latter may be made of other substances than metal.

In Fig. 4 the neck a is represented as a separate piece i'romthe body ofthe shell A.

I claim- The shell A, having slotted neck a, and shoulder f, withrecesses g, in combination with the cover 13, having pins d, asdescribed.
